SunHydrogen HYSR · USD

Hydrogen is already a significant industrial commodity. Roughly half of global consumption goes into ammonia, most of which becomes fertilizer, and methanol, with oil refining accounting for much of the remainder, and smaller and emerging use in steelmaking and as a fuel. Free hydrogen is rare on Earth, so essentially all hydrogen must be manufactured, and about 95% of the hydrogen produced in the United States is made by steam reforming of natural gas (US Department of Energy, Hydrogen Fuel Basics). That process is inexpensive, which is why it dominates, but it emits carbon dioxide, and that carbon intensity is carried into the fuels, fertilizers, and materials hydrogen is used to make.

We are developing photoelectrochemical, or PEC, panels that produce renewable hydrogen from sunlight and water. Sunlight absorbed by the semiconductor generates photovoltage and charge carriers that drive photoelectrochemical oxidation and reduction reactions at catalyst surfaces, producing hydrogen and oxygen without an externally applied electrical bias to the active device and without a separate electrolyzer or the power conditioning equipment that conventional electrolysis requires. A complete pilot or commercial system may use electricity for pumps, controls, sensors, data acquisition, gas handling, and thermal management. Because our panels are intended to produce hydrogen at the point of use, our approach is also designed to avoid the cost and emissions of delivering hydrogen from a central production plant.
